I'm sure there is a simple answer to this question, but I can't seem how to
figure out how the CPI is calculated on a monthly basis from the the CPI tables.
For instance, the annual increase in CPI in November 2012 is given as 2.7% (as
it was in October).
Using the CPI tables (using values based on 100 as of May 2005), the index in
November was 124.4 and 124.2 in October.
I'm just a little confused about how these tables relate the published annual
CPI inflation on a month-to-month basis.
